I am not active as I was in the past. I had to say it is vanity at the moment. I use them as I feel. My 100H is my go to amp, because the 4X12 cab favors lower freqs. When the wife starts looking at me funny, I go to the 40C at 20W. If I was active it will depend, some veneus today ban stack and/or required the use of their PA. The DSL 40 fit the need when miced. I still would prefer to use the 100H.
